Waste drying equipment

Abstract

The present invention discloses a waste drying device, comprising a collection bin, a filter barrel and an extrusion assembly. The extrusion assembly is composed of a first extrusion member and a second extrusion member, which are composed of a rotating barrel and a plurality of extrusion teeth. An extrusion opening is formed between the extrusion teeth, and the first extrusion member and the second extrusion member are meshed and connected by the extrusion teeth. During operation, the first extrusion member maintains contact with the inner wall of the filter barrel, and a flow area for the material to pass through is left between the second pressurizing member and the inner wall of the filter barrel. The waste drying device lifts the raw materials at the bottom through a spiral member, and at the same time cooperates with the extrusion assembly to achieve extrusion dehydration of the raw materials. Through the action of centrifugal force, the extrusion assembly is kept pushing the raw materials to rotate in the filter barrel, maintaining extrusion, achieving rapid dehydration of the raw materials, and improving the dehydration efficiency of the raw materials. And because the filter barrel does not rotate, it will not be affected by centrifugal force, causing its position to shift.

Description

Technical Field

[0001] The invention relates to dehydration technology, in particular to waste drying equipment. Background Art

[0002] Waste recycling is a paid waste disposal service. Professional, reputable waste collection centers or companies collect waste, then scientifically process and sort it to meet recycling standards. Waste recycling plays a positive role in protecting the environment, conserving energy, and driving social benefits.

[0003] After recycling, the heavy metals contained in the waste are extracted for secondary use.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] like Figures 1 to 7As shown, the waste drying device of the present invention comprises a collection chamber 1, a filter cartridge 2, and a squeeze assembly 3. The collection chamber 1 is used to collect the liquid after the waste is squeezed, while the filter cartridge 2 is used to separate the solid and liquid of the waste squeezed by the squeeze assembly 3 in the filter cartridge 2, retaining the liquid so that it flows out of the filter holes 4 into the collection chamber 1.

[0031] The interior of the collection bin 1 is hollowed out to form a collection chamber 5. A bin cover 6 is provided on the collection bin 1, and a motor 7 is mounted on the bin cover 6. This motor 7 drives the cylinder cover 8 to rotate, causing the extrusion assembly 3 to maintain centrifugal motion on the cylinder cover 8. This allows the first extrusion member 9 in the extrusion assembly 3 to contact the inner wall of the filter cartridge 2, squeezing the waste. A drainage pipe 10 is provided on the outside of the collection bin 1.

[0032] Driven by the squeezing assembly 3, the waste remains close to the wall of the filter cartridge 2 and is pressed by the first squeezing member 9. The squeezing of the waste causes liquid to be expelled from the waste and is discharged from the filter holes 4. After the first squeezing member 9 squeezes the waste, the waste remains pressed against the inner wall of the filter cartridge 2, where it is scraped by the scraping member 11 and then falls back into the filter cartridge 2. The guide 12 guides the waste to the center, where the rotation of the spiral member 13 drives the waste at the bottom upward and then out, causing it to enter the position between the squeezing assembly 3 and the filter cartridge 2. The squeezing of the squeezing assembly 3 again forces the waste against the inner wall of the filter cartridge 2 and continues squeezing.

[0033] Furthermore, due to the existence of centrifugal force, the distance between the extrusion assembly 3 and the spiral member 13 will increase when the extrusion assembly 3 is working.

[0034] The filter cartridge 2 is installed inside the collection chamber 5. A plurality of support columns 14 are provided at the lower end of the filter cartridge 2 to maintain a distance between the filter cartridge 2 and the bottom wall of the collection chamber 5. Of course, filter holes 4 can be further provided on the bottom wall of the filter cartridge 2 according to actual conditions.

[0035] The middle of the filter cartridge 2 is hollowed out to form a filter chamber 15, and a plurality of filter holes 4 are provided on the cartridge wall of the filter cartridge 2. The filter cartridge 2 is provided with a cartridge cover 8, and the cartridge cover 8 is provided with an elastic member 16. The elastic member 16 is installed on the cartridge cover 8 through a positioning column 17, so that one end of the elastic member 16 remains fixed and the other end can be deformed under force.

[0036] The extrusion assembly 3 is installed within the filter chamber 15 and comprises a first extrusion member 9 and a second extrusion member 18. The first extrusion member 9 and the second extrusion member 18 are symmetrically arranged. However, during operation, the first extrusion member 9 and the second extrusion member 18 are no longer symmetrical. The first extrusion member 9 contacts the inner wall of the filter cartridge 2, while the second extrusion member 18, limited by the length of the second strip-shaped hole 19, does not contact the inner wall of the filter cartridge 2, maintaining a certain distance between them.

[0037] The first and second extrusion members 9 and 18 are provided with a rotating shaft 20, which is provided with a retaining portion 21. The diameter of retaining portion 21 is larger than the diameter of the rotating shaft 20 and also larger than the widths of the first and second strip holes 22 and 19. The cylinder cover 8 is provided with a first and second strip holes 22 and 19 that mate with the first and second extrusion members 9 and 18. The length of the first strip hole 22 is greater than the length of the second strip hole 19. The extrusion assembly 3 is rotated by the cylinder cover 8, and centrifugal force causes it to move within the first and second strip holes 22 and 19.

[0038] The first extrusion member 9 and the second extrusion member 18 are composed of a rotating cylinder 23 and a plurality of extrusion teeth 24. The extrusion teeth 24 are evenly distributed around the rotating cylinder 23. An extrusion opening 25 is formed between the extrusion teeth 24. The first extrusion member 9 and the second extrusion member 18 are meshed and connected through the extrusion teeth 24.

[0039] Moreover, since the first extrusion member 9 and the second extrusion member 18 are connected by the extrusion teeth 24, when the first extrusion member 9 rotates on the inner wall of the filter cartridge 2, the second extrusion member 18 is driven to rotate in the opposite direction, and the waste can be pressurized from the first extrusion member 9 and the second extrusion member 18 for further extrusion.

[0040] The first extrusion member 9 and the second extrusion member 18 are symmetrically arranged on either side of the elastic member 16. The elastic member 16 is provided with symmetrically arranged elastic arms 26, the outer walls of which are in contact with the rotating shaft 20. Under the action of centrifugal force, the first extrusion member 9 and the second extrusion member 18 slide in the first strip hole 22 and the second strip hole 19, so that the first extrusion member 9 and the second extrusion member 18 push the elastic arms 26 to deform, causing the elastic area 27 to shrink. At the same time, the arc-shaped portion 28 can limit the minimum value of the elastic area 27, thereby preventing the elastic arms 26 from being overly compressed.

[0041] A rotating shaft 29 is provided at the lower end of the motor 7. A screw 13 is provided on the rotating shaft 29. The screw 13 is located in the center of the filter chamber 15. The first extrusion member 9 and the second extrusion member 18 are distributed around the screw 13. A gap 30 is formed between the extrusion assemblies 3. During operation, the motor 7 drives the screw 13 on the rotating shaft 29 to rotate counterclockwise.

[0042] The motor 7 drives the rotating shaft 29 to rotate, so that the rotating shaft 29 drives the screw 13 to rotate. The screw 13 can keep the material at the lower end transported to the upper end, and then dispersed at the upper end, thrown to the inner wall edge of the filter cylinder 2, and extruded through the first extrusion member 9 and the second extrusion member 18.

[0043] The scraping member 11 is installed in the gap 30. The scraping member 11 consists of a guide portion 12 and a scraping portion 31. The scraping portion 31 contacts the inner wall of the filter cartridge 2. The guide portion 12 extends into the gap 30. The upper end of the scraping member 11 contacts the lower end surface of the cartridge cover 8.

[0044] During operation, the first extruding member 9 maintains contact with the inner wall of the filter cartridge 2 , and a flow area 32 for materials to pass through is left between the second pressurizing member and the inner wall of the filter cartridge 2 .

[0045] The elastic member 16 is composed of symmetrically arranged elastic arms 26, which are connected by a curved portion 33. A positioning post 17 is located in the middle of the curved portion 33, which is mounted on the cylinder cover 8. The elastic arms 26 are provided with an arcuate portion 28, and an arcuate opening 34 is formed in the middle of the arcuate portion 28. An elastic region 27 is formed between the symmetrically arranged elastic arms 26. The first arcuate block 35 is shorter at the end facing the elastic region 27 and longer at the end facing away from the elastic region 27. Because the elastic piece 36 is not located in the middle of the first arcuate block 35, when the fixing post 37 on the elastic piece 36 rotates, the first arcuate block 35 is kept under a relatively high tension, preventing the first arcuate block 35 from being deformed by a large external force and disengaging from the first arcuate slot 38.

[0046] A fixing post 37 is provided in the arc-shaped opening 34. An elastic piece 36 is provided between the fixing post 37 and the positioning post 17. One end of the elastic piece 36 is fixed to the positioning post 17, and the other end is fixed to the fixing post 37. A first arc block 35 is provided at one end of the elastic piece 36, and a second arc block 39 is provided at the other end. A first arc groove 38 is provided on the positioning post 17, and a second arc groove 40 is provided on the fixing post 37. The first arc block 35 is placed in the first arc groove 38, and the second arc block 39 is placed in the second arc groove 40.

[0047] When the elastic arm 26 is subjected to force, it can drive the fixing column 37 to rotate around the positioning column 17, thereby causing the elastic sheet 36 to bend. When the motor 7 is not working, the elastic force of the elastic arm 26 and the elastic sheet 36 pushes the first extrusion member 9 and the second extrusion member 18 to reset in the first strip hole 22 and the second strip hole 19.

[0048] Before the waste is added to the filter chamber 15, it needs to be crushed into particles, and then the particles are cleaned and other operations are performed to extract the precious metals in the waste. Finally, the remaining precious metal raw materials are placed in the filter chamber 15 for squeezing to squeeze out the remaining liquid.

[0049] When placing the raw materials, the entire bin cover 6 and the cylinder cover 8 can be lifted to drive the screw 13, the scraper 11 and the extrusion assembly 3 to move upward. When placing the raw materials, the motor 7 is started to drive the screw 13, the scraper 11 and the extrusion assembly 3 to rotate slowly. During the rotation, the raw materials are pushed away to achieve the placement of the screw 13, the scraper 11 and the extrusion assembly 3.

[0050] Furthermore, dry gas may be introduced into the collecting chamber 5 so that the gas enters the filter chamber 15 through the filter holes 4 to dry the raw materials raised inside and improve the dehydration efficiency.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
